SEED-DRILL.

SPECIFICATIQN forming partof Letters Patent N 281,602,:1ated July 17, 1883. Application filed March 17, 1883. (Model) To all whom it 11mg concern:

Be itknown that I, JOHN M. ALLEN, of Washington Court-House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Seed- Drills; and I do herebydeclare the following to be a full, clear, and exact description of the I invention, such as will enable others. skilled in the art.to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in seed-drills; and it consists in the combination of the shaft and revolving cup, the revolving gage-cylinder, and the non-rotating slide provided with an arm for the purpose of preventing the casing which surrounds the cup from filling from the front, all of which will be more fully described hereinafter.

The object of my invention is to have the cup revolve instead of remaining stationary, as heretofore, and thus carry the grain around and discharge it without thedanger of breaking or injuring it in any way.

Figure 1 is a side elevation of my invention complete. Fig. 2 is a vertical longitudinal section of the same. Figs. 3 and 4 are detailed views of the same.

A represents the seed-box, which will be of any desired length, and which has openings B through it at regular intervals to correspond to the number of dropping devices employed. Secured to the under side of this seed-box is the casing O, which has the opening D through its lower side for the free discharge of the seed. The operating-shaft E passes through the center of this casing, and is provided with a spline, G, so as to cause the seed-cup H and the cylinder I to revolve with it. Instead of the cupremaining stationary, as heretofore, it is here made to revolve with the shaft inside of the casing, and serves to carry the seed aroundand discharge it at the proper point without the slightest danger of breaking or injuring a single grain. The cylinder I has the flange J formed upon its innerend and slides back and forth upon the shaft independently of the cup. The farther this cylinder is forced inward into the cup the larger the amount of grain fed, and the farther the cylinder is moved outward the nearer its flange This slide moves freely back and forth upon the shaft, and has no other movement than the sliding one which is given to it by the arm or lever O, which is rigidly secured to the slid ing rod I. To the upper end of this arm or lever is connected, in any suitable manner, the lower end of the prongedindicator-lever R, the upper end of which moves over a scale on' the seed-box, and indicates the amount of seed that is being sowed to the acre. When the .rod is pushed endwise, it not only moves all of the gage-cylinders, but moves the indicatorlevers so as to show just the exact amount that is being planted.

By means of the construction above 6.6-

scribed it will readily be seen that the grain falls directlyinto the cup, and then is carried around by the cup until it reaches the opening in the casing, when the grain is discharged without being broken or otherwise injured;

I am aware that there is nothing new in a stationary frame and a revolving cup or cylinder which is attached to the driving-shaft and used in connection with the adjustable guard-plate, and this I disclaim.

Having thus described my invention, I claim The combination of the stationary frame 0, the rotating seed-cup H, the shaft E, the cylinder I, having a flange upon its inner end, and

which is swiveled. to the slide X, and the slide,

which is provided with the arm N, substantially'as shown and described In testimony whereof I affix my signature in presence of two witnesses.
